Abstract

Al-Ahsa Road, which is located in north-eastern Riyadh, was constructed in March 1981 as part of the Fourth Stage of the Riyadh Urban Road Improvement Project. The road is 2.85 km long. Reconstruction consisted of the installation of a 170 mm thick asphalt basecourse and a 40 mm thick hotmix asphat wearing course. Several months after construction, following the first winter, shrinkage and transverse cracking was observed on some areas. Corrugations also formed at and near most of the intersections. A study was initiated to investigate the possible causes of this distress, including an examination of the construction records and an analysis of the results of laboratory and field testing carried out during and after construction. This note summarises the results of this investigation. The application of slurry seal could be considered as an immediate maintenance technique for shrinkage and transverse cracking.
